Your Caranthir is one seriously scary child, but he's adorable all the same. Is he refering to the language of the Valar or one of the elvish languages as foreign?

I like the idea of Feanor and family going off to Formenos every summer, and also that Nerdanel threatens not to go if Feanor doesn't do what she wants. It's a nice piece of foreshadowing.

Do you have a particular reason for using the sindarin words for mother and father? I've wondered why so many fic writers do, but never got round to asking before.
